The excellent text entry program for touch screen and Tablet PC devices by IBM that was previously known as SHARK is now called ShapeWriter. I am not sure why IBM decided to change the name but it certainly sounds more commercial, doesn’t it? ShapeWriter is the technology that allows text input by sliding a stylus over a customizable keyboard. The program then determines the correct word by the shape of the stylus path over the keyboard. I wrote a detailed review of ShapeWriter last year.
